Monocular visual loss as the presenting symptom of COVID-19 infection.

ABSTRACT

BACKGROUND AND IMPORTANCE Additional time is needed to determine the exact impact of COVID-19 on acute cerebrovascular disease incidence, but recently published data has correlated COVID-19 to large vessel occlusion strokes. CLINICAL PRESENTATION We report the first case of central retinal artery occlusion (CRAO) as the initial manifestation of COVID-19 infection. Subsequent neuroimaging revealed a large thrombus extending into the internal carotid artery. CONCLUSION: This case illustrates the need to suspect COVID-19 infection in patients presenting with retinal arterial occlusion, including individuals who are asymptomatic or minimally symptomatic for COVID-19 infection.
